Here are some hairstyle ideas, including bob hairstyles, to inspire you.
The "bouclé bouclé" hairstyle involves tying short hair close to the roots, in several sections, creating fractal patterns (half-circles, triangles, squares, etc.). The hair for this hairstyle should be curly to achieve the appearance of pom-poms or natural balls. This doesn't give the same result with straight hair or large curls.
The "ball" or "poop" hairstyle of sheep, goat, and kid also has a multitude of names depending on the language and region of the world, such as:
"Klui-Klui" in Togo,
"Ponpon" in Guinea (Conakry),
"Gbofloto" (Translation: Doughnuts), "Boules boules" in Ivory Coast,
"Toufi ya ntaba" in Lingala(Translation: Goat poop) in the Congos (Brazzaville & Kinshasa).
